Abstract
The invention provides a fertilizing method of forage grass. According to the fertilizing method, urea is taken as a nitrogen fertilizer, calcium superphosphate is taken as a phosphorous fertilizer and potassium sulfate is taken as a potassium fertilizer, wherein the use amounts of nitrogen, phosphorous and potassium are metered in parts by weight according to a ratio of N to P2O5 to K2O being 1.986 to 1 to 2.114. The fertilizing method comprises the following steps of firstly, applying all the phosphorous fertilizer and 45% of the nitrogen fertilizer and the potassium fertilizer taken as base fertilizers into culture soil; applying 25% of the nitrogen fertilizer and the potassium fertilizer taken as first time topdressing at a tillering stage; and averagely distributing and applying the residual 30% of the nitrogen fertilizer and the potassium fertilizer after each time of harvesting. According to the fertilizing method provided by the invention, the suitable nitrogen fertilizer, phosphorous fertilizer and potassium fertilizer are selected to be reasonably matched with the use amounts of the nitrogen fertilizer, the phosphorous fertilizer and the potassium fertilizer so as to meet nutrition requirements of orchard grass very well; meanwhile, a fertilizing manner is matched to sufficiently improve the nutrition absorption of prior periods and post periods of the orchard grass; the quality and the yield of the orchard grass are improved effectively; the energy source consumption is reduced, the environmental pollution is avoided and the soil fertility is improved, so that the economic benefits of production of the orchard grass are improved greatly.
Description
The present patent application be for application number be 201110355876.4, the applying date is the divisional application of the patent of invention on November 10th, 2011.
Technical field
The present invention relates to a kind of herbage fertilizing method, be specifically related to the fertilizing method of orchardgrass.
Background technology
Orchardgrass claims again halymenia dentata, orchard grass, originate in Europe, north African and Temperate Region in China, Asia, it is one of world-renowned temperate zone good forage, the plantation history of existing more than 200 year in North America, being one of U.S. commerial growing herbage at present, is also one of good mixed seeding grass seeds of sylvan life meadow and high light efficiency sown pasture.
In recent years, orchardgrass is extensively cultivated application on China Sichuan, Chongqing, Shanxi, Gansu, Heilungkiang and other places, and has obtained certain economy, ecology and social benefit.But in plantation orchardgrass process, orchardgrass is not furtherd investigate, according to local soil fertility, the potassium balance of nitrogen phosphorus is joined and execute, thereby orchardgrass productivity and grass product matter are not high, also brought environmental pollution, orchardgrass cultivating economic benefit has much room for improvement.
Summary of the invention
The object of the present invention is to provide the fertilizing method of a kind of herbage.
The object of the invention is to realize by following technical measures, be below weight percentage, except special instruction:
A fertilizing method for herbage, is characterized in that: adopt urea (N content is 46%, is commercially available prod) as nitrogenous fertilizer, superphosphate (P

2o content is 25%, is commercially available prod) be potash fertilizer, wherein the consumption of nitrogen, phosphorus and potassium is for pressing N, P
2o
5, K
2o is than 1.986: 1: 2.114, in weight part ratio; First using whole phosphate fertilizer, apply in cultivating soil as base manure with 45% nitrogenous fertilizer and potash fertilizer, the nitrogenous fertilizer in tillering stage using 25% and potash fertilizer is as topdressing and apply for the first time, the nitrogenous fertilizer of residue 30% and potash fertilizer each harvesting afterwards mean allocation apply; State cultivating soil specifically, it is the types of soils of reservoir area of Three Gorges: brown paddy soil, soil property is sandy loam, soil nutrient status is: 0～20cm soil layer content of organic matter is 9.11%～10.02%, ammonium nitrogen 0.08g/kg～0.18g/kg, available phosphorus 0.253g/kg～0.531g/kg, available potassium 0.021g/kg～0.062g/kg, pH is 5～7; Described amount of application of nitrogen fertilizer is 522kg/hm
2, phosphate fertilizer amount is 236kg/hm
2, K Amounts is 640kg/hm
2.
Specifically, the fertilizing method of a kind of herbage, carries out as follows:
(1) unit are amount of urea is 522kg/hm
2, superphosphate consumption is 236kg/hm
2, potassium sulfate consumption is 640kg/hm
2;
(2) in the previous day of planting, using whole phosphate fertilizer, 45% nitrogenous fertilizer and potash fertilizer as base manure and fine earth impose on equably cultivating soil railway carriage or compartment face after mixing, cover; Soil types: brown paddy soil, soil property is sandy loam, soil nutrient status is: 0～20cm soil layer content of organic matter is 9.11%～10.02%, ammonium nitrogen 0.08g/kg～0.18g/kg, available phosphorus 0.253g/kg～0.531g/kg, available potassium 0.021g/kg～0.062g/kg, pH is 5～7;
(3) in tillering stage, using 25% nitrogenous fertilizer and potash fertilizer as topdressing and apply for the first time;
(4) after each harvesting, mean allocation applies the nitrogenous fertilizer and the potash fertilizer that remain 30%: when harvesting twice, use 15% at every turn; When harvesting three times, use 10% at every turn, the like.
Above-mentioned orchardgrass kind can be peace bar, Baoxing, model, Taurus, Chuan Dong, is preferably model orchardgrass.
The present invention has following beneficial effect:
The present invention is by selecting suitable nitrogen, phosphorus, potash fertilizer, thereby the consumption of reasonably combined nitrogen, phosphorus, potash fertilizer has met the nutritional need of orchardgrass well, and Fertilizers mode has fully improved the grow nutrient absorption of forward and backward phase of orchardgrass simultaneously; Accomplish well the balanced application to nitrogen, phosphorus, potash fertilizer in orchardgrass production, give full play to the fertilizer efficiency of nitrogenous fertilizer, phosphate fertilizer and potash fertilizer, quality and the output of orchardgrass are effectively improved, reduce energy resource consumption, avoided environmental pollution, improved soil fertility, greatly improved the economic benefit that orchardgrass produces.
